Issue with extract and convert of date field

I am required to find the time when SQL Service was shut down ungracefully. There is nothing in the event viewer or the SQL Logs till it restarts.

So

I am extracting date from this statement:The previous system shutdown at 1:30:21 PM on ‎3/‎29/‎2017 was unexpected.I am able to get the date via extraction and it coverts it to datetime using powershell.But when I insert that datetime into a sql table it gives the following error:

Msg 241, Level 16, State 1, Line 18Conversion failed when converting date and/or time from character string.

By opening the string in UltraEdit for Hexa characters, I get to see this:1:30:21 PM on â€Ž3/â€Ž29/â€Ž2017

I suspect this is the reason for its failurethe characters â€Ž. Not sure how to overcome this.

I want to find the exact time when the previous unplanned system shutdown was.
When a system shuts down ungracefully, it leaves (and cannot leave) any error message in the event log till much after it restarts with a message "The previous system shutdown at 1:39:06 PM on 07/13/2017 was unexpected."
This is the only place where I can find this date.
